Hazem Farraj describes himself as "American by birth - Palestinian by blood - Christian by choice". He moved to Jerusalem and learned his Islam in the mosques controlled by the Palestinian Authoritiy. But he didn't like what he was learning, rebelled and converted to Christianity. He has a completely authentic voice and point of view. NER's audience may appreciate using his videos as they have an engaging authenticity to them.
This is his entire series on why ISIS is Islam. It's made up of a number of shorter clips each of which stands on its own.
This video, not from that series, where he explains what being an #ExMuslim is really about is worth watching.
